dotted lines the arrangement of operating 15 gear parts and driving means below the bottom of a container or tub, also partially in transverse section to show operating means for effecting relative connection or disengagement of driving connection for an agitator member. 1

Fig. 2 is a side elevation, showing a container and parts connected therewith, said container-being broken away to showinterior operating parts, said interior operating 25 parts being partially in section to better illustrate structure and arrangement of parts;

'Fig. 3 is a detail plane view, showing an operating means for effecting engagement disengagement of the gear parts; Fig. 4 is a plan view of the same subjectmatter as disclosed in Fig. 3, the parts being merely in different position;

I Fig. 5 is a side elevation showing the same subject-matter as disclosed in Fig. 3, a por- 35 tion in said figure being broken away in order to show detail parts.

' Referring to the drawings, refers generally-to a circular container or-tub; 13 are leg supports for the container, and 14 is a removable lid or cover.

The agitator structure is essentially the same as thatdisclosed in my prior Patent #1,563,624, issued December 1, 1925, and

.. comprises an agitator member 15 having a base 16 bafiies 17, and a shank 18 which is adapted to be driven by the agitator shaft 24. Shaft 24 is supported by bracket 25 and carries a gear27 at 1ts lower end.

28 is an arcuately fashioned rack or segmental gear related'to gear 27 for optional eludes relative intermesh. 29 is a reach member,- connected with the rack centered and supported in conjunction with-eccentric member 30, the latter being fixed to'rod 31, said rod being supported at its opposed ends respectively in conjunction with bracket members 32 and 33. A shifting handle 34 is fixed to the upper ortion of rod 31, and serves to turn the latter or the purpose of longitudinal re-' ciprocation of reach member 29 to cause gear 27 to engage or release rack 28, to the end that driving member 24 may be reciprocated or, through disengagement with respect to said gear and rack, said driving member may be at rest.- To facilitate permanency of lacement of shifting lever 34:, a spring 100 is provided, including a spring and ball, as shown in Fig. 2, the same being adapted to engage, at option, a series of depressions in the lower face of bracket member 33.

The means for actuating the rack 28 initman member 35, pivoted at one end to t e rack, and at its opposed end to the crank member 36. Any suitable means may be employed to drive crank member 36.

Special attentionis called to the clutch means herein shown that provides for optional relative engagement as between the gear on the driving member and a rack, which affords a simple and improved means for regulating such connection and reduces materially the wear that ordinarily attends such shift gear connection.

With respect to the manner of engagement of the pivoted segment gear with the driven gear attached to the a 'tator shaft, it will be noticed immediately t at due to the eccentric mounting for the segment gear, when said segment is reciprocated and the eccentric moved to permit engagement of the segment with the driven gear, the teeth on the segment will move in a line tangential with reference to the axis of reciprocation of the driven gear.

What I claim is:

1. In a washing machine, a tub, a vertical agitator shaft having its lower end extending below said tub, a gear fixed to the lower end I of said shaft, a rack member adapted to engage and actuate said gear, a movable eccen- 10-;

so adapted to be engage trio member associated with said rack'mem- Q bar in fixed pivotal relation, a lever for oscillating said rack, and means positioned adjacent the upper portion of said tub for rotat- 5 ing said eccentric member'to thereby move said rack into and out of engagement with said gear.

' 12. In a washing machine, an agitator shaft, a gear fixed to the bottom of said shaft, an

bottom of the machine, a rack member pivoted to said eccentric member and adapted to engage said gear, means for oscillating said rack, means com rising a shifting handle of two positions. a

3. In a washing machine, a tub, an agitator shaft having one of its'ends extending .below' said tub, a ear fixed to said end,'an .oscillating rack adapted to engage and actuate said gear, an eccentric member forming a pivot for said rack, means for oscillating said rack, and means for rotating said eccen-- tric member to'thereby move said rack into and out of engagement .with said gear, said rotating means including a shiftinghandle positioned adjacent the'upper portion of the 4. In a washin machine, in combination, a tub, an agitator s aft havin one end extended to the lower end of the shaft, a segmental gear adapted to pivotally mounted adjacent the lower outer edge of the tub forming a pivot for said segmental gear, means for oscillating said segmental gear, and a handle for pivoting said eccentric to move said -se ental gear into and out of engagement witi said gear:

5. Ina washin machine, in combination, a tub, an agitator s aft havin one end extending. below said tub, a gear xed to the lower; end of the shaft, a segmental driving gear adapted to engagean actuate said gear, a rotatably mounted eccentric upon which said segmental gear is pivoted, means foroscillating said segmental gear and means for ro-- tating said eccentric to move thesegmental gear into and out of engagement with the eccentric member movably mounted near the near the top of said machine for moving said eccentric member to thereby move said rack into and out of engagement with said gear, and means for locking said handle in either permitting the gearto be moved into an out of driving, relation withsaid pinion, said eccentric and-the pivotal connection between the pitman and segmental gear causing the segmental gear to have a compound movementradi ally and tangentially of the pinion during the engaging operation.

7. In a washing machine, in combination, an agitator shaft, a pinion secured thereto, a segmental driving gear adapted to be engagedwith and disengaged from said pinion,

a pivotal mounting for said segmental gear,

a pitman for oscillating said gear having one end pivotally connected to said segmental gear at a point outwardly-disposed from the gear axis and an eccentricmounting for the 'pivot of the gearpermitting the gear to be moved 'into and out of driving relation with saidcpinion, said eccentric and the pivotal connection betweenthe pitman and segmental gear causing the segmental gear to have a compound movement radially and tangentially of the pinion during the clutching operation.

8. In a washing machine, incombination,

means for driving an .agitator including a pinion, a segmental gear adapted to be engaged with anddisengaged from said inion, a pivotally mounted pitman pivotal y connected to said gear eccentrically thereof for oscillating said gear, and means for shifting said gear with a compound movement aroun the pivotal axis of said pitman andaround the pivotal connection of said pitman to said gear.

9. In a washing machine, in combination, means for driving an agitator including a pinion, a segmental gear adapted to be moved into and out of engagement with said pinion, means for oscillating said gear, and means for moving said gear into enga ement with said pinion with a movement su stantiall radial of the pinion during the first part 0 the engaging operation and with a movement substantially tangential of the pinion during the latter part of the engaging o eration.

In testimony whereof I have aflixed my signature.
